Drag the Curve
Select and drag a point up/down to alter the color value of a tone. If you drag the highest
point on the far right end of your curve down, you reduce a color where it is strongest. If
you drag the lowest point on the far left end up, you intensify a color where it is weakest.
Switch Between Colors
You can freely switch between curves to work on them individually, without losing your
previous edits. Create a blue curve that compliments your red curve to mix and match
tones, or just work on overall contrast and brightness by using the RGB curve.
